1 INTRODUCTION
1.1 GENERAL
This Visual Impact Scoping Report (VISR) forms part of the Scoping and
Environmental Impact Assessment that is being undertaken for the proposed Hyperion
Solar Development 2 and associated infrastructure project by Savannah
Environmental (Pty) Ltd on behalf of Cyraguard (Pty) Ltd.
In terms of the amended National Environmental Management Act (NEMA) Act No.
107 of 1998, the proposed development requires environmental authorisation. A key
impact to be assessed comprises the visual impact that the proposed facility will have
on surrounding areas.
This desktop VISR has been prepared for inclusion in the Scoping Report compiled for
the proposed project.
1.2 PROJECT LOCATION
The proposed project is located in the Gamagara Local Municipality and the John Taolo
Gaetsewe District Municipality. (Map 1: Locality Map).
The following terminology should be noted:
a) Project site – refers to the Remainder of the Farm Lyndoch 432
b) Development area – refers to the area within the project site which is
specifically for PV 2.
c) Development footprint – refers to the actual facility footprint.
The approximate geographic coordinates for the centre of the proposed development
area are;
1.3 BACKGROUND OF SPECIALIST
Jon Marshall qualified as a Landscape Architect in 1978. He is also a certified
Environmental Assessment Practitioner (EAP) of South Africa. He has been involved in
Visual Impact Assessment over a period of approximately 30 years. He has developed
the necessary computer skills to prepare viewshed analysis and three dimensional
modelling to illustrate impact assessments. He has undertaken visual impact
assessments for major buildings, industrial development, renewable energy, mining
and infrastructure projects and has been involved in the preparation of visual
guidelines for large scale developments.
A brief Curriculum Vitae outlining relevant projects is included as Appendix I.
1.4 TERMS OF REFERENCE AND RELEVANT GUIDELINES
The brief is to assess the visual impact that the proposed project will have on
surrounding areas.
Work was undertaken in accordance with the following guideline documents:
South 270 33’ 14.41”
East 230 04’ 23.04”
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 5
a. The Government of the Western Cape Guideline for Involving Visual and
Aesthetic Specialists in EIA Processes (Western Cape Guideline)
(Oberholzer, 2005). This is the only local relevant guideline available in
South Africa, setting various levels of assessment subject to the nature
of the proposed development and surrounding landscape (Appendix
II); and
b. The Landscape Institute and Institute of Environmental Management
and Assessment (United Kingdom - UK) Guidelines for Landscape and
Visual Impact Assessment (GVLIA) which provides detail of international
best practice (UK Guidelines) (Landscape Institute and Institute of
Environmental Assessment and Management, 2013).
1.4.1 Western Cape Guidelines
The Western Cape Guidelines provide a useful guide as to the level of impact
necessary for various types of developments and in various types of landscape. It also
provides guidance as to the necessary consideration and content of an assessment.
This information is applied in Section 6, Methodology.
At this initial stage it is assumed that a Level 3 Assessment will be required in
accordance with these guidelines. A Level 3 Assessment requires:
a) Identification of issues raised in scoping phase, and site visit;
b) Description of the receiving environment and the proposed development;
c) Establishment of view catchment area, view corridors, viewpoints and
receptors;
d) Indication of potential visual impacts using established criteria;
e) Inclusion of potential lighting impacts at night;
f) Description of alternatives, mitigation measures and monitoring programmes;
and
g) Review by independent, experienced visual specialist (if required).
This desktop Scoping Assessment focuses on items a) to e) inclusive in order to
provide stakeholders with relevant information to enable comment and in order to
provide the necessary focus for the site investigation and compilation of the Visual
Impact Assessment.
1.4.2 UK Guideline
This document provides the following criteria which, at least, should be borne in mind
as it could help in carrying out the process of assessing the Landscape Effects as
follows:
Consider the physical state of the landscape. This includes the extent to which
the typical character is represented in individual areas, the intactness of the
landscape from visual, functional and ecological perspectives and the condition
of individual elements of the landscape;
Consider scenic quality which depends upon perception and reflects the
particular combination and pattern of elements in the landscape, its aesthetic
qualities, its more intangible sense of place or ‘genius loci’ and other more
intangible qualities;
Consider the rarity of the landscape, it might be valued because it is a rare
type, or because it contains rare elements, features or attributes;
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 6
Consider representativeness, as a landscape may be valued because it is
considered to be a particularly good example of its type either in terms of its
overall character or because of the elements or features it contains;
Consider conservation interests, i.e. the presence of features of wildlife, earth
science or archaeological or historical and cultural interest can add to the value
of the landscape as well as having value in their own right.
Consider perceptual aspects as a landscape may be valued for its perceptual
qualities, notably wildness and/or tranquillity; and
If public opinion has been sought consider if there may be a consensus of
opinion, expressed by the public, informed professionals, interest groups, and
artists, writers and other media, on the importance of the landscape.
As regards the Visual Effects, the Guideline suggests the selection of the final
viewpoints used for the assessment should take account of a range of factors
including:
Accessibility to the public;
Potential number and sensitivity of viewers who may be affected;
Viewing distance (i.e. short, medium and long distance views) and elevation
View type (for example panoramas, vistas, glimpses);
Nature of viewing experience (for example static views, views from settlements
and points along sequential routes); and
Potential for cumulative views of the proposed development in conjunction with
other developments in the surrounding landscape.
1.5 THE NATURE OF VISUAL IMPACT
Visual impacts may relate to a general change in the character of an area or in the
change in a specific view for a person or group of people.
Visual impacts can be positive or negative and a degree of subjectivity is required in
deciding this point. The approach of any visual assessment should, as objectively as
possible, describe a landscape and (as far as is possible) reflect the likely majority
view regarding the positive / negative aspects of an impact. This can be difficult
particularly in South Africa due to different values and cultures associated with various
sectors of the population. For example, poorer and particularly rural based sectors of
the population are possibly more concerned with the productive nature of a landscape
than its appearance, whereas the wealthier sectors might be more concerned with
scenic value particularly as it is associated with property values. If possible, the values
and opinions of all impacted sectors of the community should be considered.
General change to a landscape might have greater or lesser significance subject to
issues listed in Section 1.4.2.
In terms of change to a specific view, this might be defined as either visual intrusion
or visual obstruction.
a) Visual intrusion is a change in a view of a landscape that reduces the quality of
the view. This can be a highly subjective judgement. Subjectivity has been
removed as far as possible in this assessment by classifying the landscape
character of each area and providing a description of the change in the
landscape that will occur due to the proposed development.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 7
b) Visual obstruction is the blocking of views or foreshortening of views. This can
generally be measured in terms of extent.
More often than not such an impact will be a combination of intrusion and obstruction.
Obstruction can be measured in terms of the extent of an existing view that is
screened by a development. However, judging intrusion requires a degree of
subjectivity. It is however possible to relate this judgement to the manner in which
proposed change would impact on the use or enjoyment of an area, which again
requires an understanding of local values.
1.6 GENERAL SCOPING OBJECTIVES
This Scoping Study identifies and evaluates potential environmental impacts
associated with all aspects of the Proposed Project. In terms of the EIA Regulations,
feasible and reasonable alternatives should be assessed within the Scoping Study. The
scope of an environmental assessment is defined by the range of issues and feasible
alternatives to be considered, and the approach towards the assessment that will
follow.
The characteristics of a scoping exercise are as follows:
a) Feasible and reasonable alternatives are identified and selected for further
assessment;
b) Important characteristics of the affected environment are identified;
c) Significant issues that are to be examined in the assessment procedure are
identified; and
d) It provides the basis for determining terms of reference for the assessment
procedure.

2. PROJECT DESCRIPTION
2.1 PROJECT DESCRIPTION
The proposed Hyperion Solar Development 2 Project is part of a larger overall PV
development that includes three additional PV projects.
Each project will have a maximum generation output capacity of 75MWs and will
include Battery Storage for each project. The projects will each include:
Arrays of PV panels (static and tracking PV system) with a contracted
capacity of up to 75MW.
Mounting structures to support the PV panels.
Cabling between the project components, to be laid underground where
practical.
On-site inverters to convert the power from a direct current to an
alternating current.
An on-site substation to facilitate the connection between the solar energy
facility and the Eskom electricity grid.
A new 132kV overhead power line (OHPL) between the on-site substation
and the existing Ferrum Substation1.
Battery storage mechanism with a storage capacity of up to 300MWh.
Water purification plant.
Site Offices and Maintenance Buildings, including workshop areas for
maintenance and storage.
Batching plant.
Temporary laydown areas.
Internal access roads and fencing around the development area.
Access road from the project site to the N14 (two alternatives will be
considered).
Each proposed facility will be connected to an on-site collector substation via a
132kV power line. The collector substation will be connected to the Eskom Ferrum
substation in Kathu via a double circuit power line.
The Photovoltaic (PV) panels will be attached to a support structure up to 5m off
the ground set at an angle so to receive the maximum amount of solar radiation
(fixed technology), or set to track the sun (tracking technology) in order to
increase the amount of energy produced. The PV panels can either comprise a
fixed/static support structure set at an angle (fixed-tilt) so to receive the maximum
amount of solar irradiation, or a tracking axis, where the system tracks the sun.
The angle of the panel is dependent on the latitude of the proposed facility and the
angles may be adjusted to optimise for summer or winter solar irradiation
characteristics.
The PV panels are designed to operate continuously for more than 20 years,
unattended and with low maintenance requirements.
1 The construction of the 132kV overhead power line will be assessed as part of a separate
Basic Assessment process which will consider feasible alternatives for the power line route.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 10
2.2 LIKELY SCALE OF DEVELOPMENT AND NATURE OF VISUAL IMPACTS
The locations of the various elements need to be confirmed prior to the assessment
stage. As this is fundamental to visual impact, broad assumptions have been made
based on experience of similar projects in order to progress the Scoping
Assessment.
In visual terms, a PV array is generally comprised of a combination of elements
that can be obvious in the landscape. The most obvious are likely to include:
2.2.1 The PV Units
PV units are generally aligned in rows with only sufficient space between the rows
to allow access for maintenance and replacement. This means that when an array
is viewed from ground level, it appears as a single row of units. However when
viewed from a slightly elevated position, the individual rows combine to increase
the visual mass particularly if an overview of a facility is possible.
In addition to the way that a mass of PV units may change the landscape, reflection
and glare is often highlighted as a potential issue. Whilst, PV units are designed to
absorb as much energy as possible, the intensity of glare can be an issue when
light is received at glancing angles as less light is absorbed and more light
reflected. These conditions are likely to occur when the elevation of the sun is low
during early morning and late afternoon for viewers at a similar level as the array.
For observers that are significantly higher than the array however, such as those
on an aircraft flight path, the timing of adverse conditions will vary subject to the
location of the aircraft relative to the array.
If it is problematic, glare is likely to be a temporary impact in most instances only
causing nuisance during a certain time of day and possibly time of year.
2.2.2 Substation and Inverters
An on-site substation is necessary for each project to step up current to 132kV so
that it can be fed into the National Grid. It is anticipated that this on-site
substation will be an outdoor type within a fenced compound. From experience it is
expected that the tallest structure other than connecting power lines would be in
the region of 2m to 3m.
There will be a number of inverters within each project to convert direct current
(DC) to alternating current (AC). Each inverter is likely to be in the order of 2 - 3m
in height.
2.2.3 Offices and Maintenance Buildings (Including Workshops)
A small workshop will be necessary to repair and maintain the electrical and
support elements within each project. This is likely to be housed in a small building
adjacent to each PV project.
Other ancillary buildings within each project will include an office, ablutions, first
aid and rest room facilities. These are likely to be located within one or a small
group of single storey buildings and are therefore likely to be a similar height as
the proposed PV array.
2.2.4 Overhead Power Lines
A new 132kV overhead power line will be required to connect the output from each
of the facility sub-stations to the National Grid. The connection point is likely to be
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 11
the Eskom Ferrum substation in Kathu, approximately 18km to the south of the site
area.
The necessary overhead power line will be the subject of a separate basic
assessment process.
2.2.5 Security Lighting
The facility will likely be lit by security lights to a level sufficient to ensure that
security cameras can operate at night. This is likely to result in the array being
obvious at night from surrounding areas.
2.2.6 Road Access
In a flat landscape, road construction is likely to only have an impact on the area
immediately surrounding it. Whilst a busy road might be obvious from a distance
due to vehicles being obvious, for much of the time, a road that is lightly used
where disturbance of surrounding vegetation has been minimised is unlikely to be
obvious past 100m from the road edge.

3 DESCRIPTION OF RECEIVING ENVIRONMENT AND
RECEPTORS
It is possible that landscape change due to the proposed development could impact
the character of an important landscape. Landscape character can be derived from
specific features relating to the urban or rural setting and may include key natural,
historic or culturally significant elements. Importance might also relate to
landscapes that are uncommon or under threat from development.
This section will:
Provide an initial description of the types of landscape that may be
impacted;
Provide an initial Indication of the likely degree of sensitivity; and
Provide an initial description of how the landscape areas may be impacted.
The study area is defined by the limit of visibility of the proposed project. As an
initial guide, the limit has been set at 9km from the proposed site being the
approximate limit of visibility of a 6m high structure. Refer to Section 5 for the
justification for this distance.
3.1 LANDSCAPE CHARACTER
Landscape character is defined as “a distinct, recognisable and consistent pattern of
elements in the landscape that makes one landscape different from another”2.
Landscape Character is a composite of a number of influencing factors including:
Landform and drainage;
Nature and density of development; and
Vegetation patterns.
3.1.1 Landform and Drainage
Refer to Map 2 for analysis of the landform and drainage.
The proposed project is located on a broad valley floor that is drained by the
Vlermuisleegte which is an intermittent stream that flows from south to north
through the proposed project site.
The valley floor falls from southeast to northwest at a gentle gradient of
approximately 1:200.
The visual implications of landform are;
Because the N14 is located approximately 7km to the south at an elevation
approximately 30m higher than the proposed project, it is highly likely that
the project will be visible from this road.
The shallow gradient is likely to mean that the project will be viewed largely
in elevation with little or no extended overview.
Refer to Map 2, Landform and Drainage.
2 UK Guideline
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 14
3.1.2 Landcover
The population density of the area immediately surrounding the proposed
development varies.
Kathu is the largest town of five towns within the Gamagara Local Municipality. At
the 2011 census, the municipality had a total population of approximately 41,617
people approximately 71% of which are based in urban areas.
The area of the Municipality is 2,619km2.
Rural homesteads were found to have an average occupancy of 3.5 people. This
means that there is a rural homestead for approximately every 0.75km2.
Given the Province's dry conditions and dependence on irrigation, many Northern
Cape farmers are branching out into value-added activities such as game farming.
This is apparent in rural areas surrounding the proposed development as low
intensity grazing appears to be mixed with game farming, hunting operations and
bush lodges.
Kathu is primarily a rural service centre. It is likely also that a proportion of its
economy is derived from local mining operations as well as its position on the N14
as it acts as a transit stop for travellers including tourists.
Kathu has a regional airport, located approximately 11.7km to the west of the
proposed project.
Apart from agriculture, mining is the largest industrial activity in the area. Kathu is
the centre of this activity. Mines in the area include iron ore and manganese. The
mine to the west of Kathu and south of the proposed project is the Mamatwan
Manganese Mine that is operated by Anglo American.
In addition to Mamatwan, there are numerous areas of degraded land as indicated
on Map 3. It is possible that these areas have resulted from informal mining
operations.
All major mining activities are a significant distance from the propose development
area and are unlikely to have a significant influence on the character of the
landscape surrounding the project.
Visual implications of landcover include the potential that homesteads on adjacent
farms could have tourism importance if they have been developed with bush lodges
and are used for game viewing or hunting operations.
Refer to Map 3, Landcover.
3.1.3 Vegetation Patterns
According to Mucina and Rutherford3 (2006), the proposed project is located in a
relatively natural area. The vegetation types include:
3 Vegetation types of South Africa (including Prince Edward and Marion Islands), Lesotho and Swaziland, 2006
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 15
Kuruman Thornveld;
Kathu Bushveld; and
Kuruman Mountain Bushveld.
All vegetation types are usually open tree and shrub cover with a sparse grass
layer.
Visual implications include;
Where the viewer is amongst natural vegetation, it is possible that there will
be a degree of screening provided by the natural vegetation.
Where the viewer is set back from natural vegetation or where ground
elevation provides a slightly elevated overview of the landscape, the extent
of screening provided by natural vegetation is likely to be limited.
3.1.4 Future Development
With reference to the Department of Environmental Affairs (DEA) web site that
records the location of current renewable energy applications
(https://dea.maps.arcgis.com), it is obvious that there are currently twelve other
renewable energy projects within 30km of the proposed development. From
reference to Google Earth, a number of these projects are under construction.
These developments are likely to result in a degree of industrialisation of what in
essence is currently a rural landscape. The majority of the projects are located well
away from main roads, so it is possible that the average person will not realise the
extent of development. There are however six (6) other projects that are located at
a similar distance or closer to the N14 as the proposed Hyperion Projects. Whilst
no detailed work has been undertaken, this is likely to mean that other projects will
be visible from the road.
3.2 LANDSCAPE CHARACTER AREAS & VISUAL ABSORPTION CAPACITY
Landscape Character Areas (LCAs) are defined as “single unique areas which are
the discrete geographical areas of a particular landscape type”4.
Visual Absorption Capacity (VAC) is defined as the landscape's ability to absorb
physical changes without transformation in its visual character and quality. Where
elements that contrast with existing landscape character are proposed, VAC is
dependent on elements such as landform, vegetation and other developments to
provide screening to a new element. The scale and texture of a landscape is also
critical in providing VAC, for example; a new large scale industrial development
located within a rural small scale field pattern is likely to be all the more obvious
due to its scale.
The landscape within the Approximate Limit of Visibility appears relatively uniform.
Overlaying the landform, landcover and vegetation, all potentially affected areas
appear to be a composite of relatively flat topography, natural landcover which is
generally comprised of Kathu Bushveld. This combination of characteristics could
provide a significant degree of VAC due to the following factors:
4 UK Guidelines.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 16
Because the array will be viewed in a flat landscape it is likely to be seen in
profile, meaning that at any distance it will appear as a narrow dark band in
the landscape;
The Kathu Bushveld is likely to include woody vegetation that extends above
head height. This taller vegetation may not be very dense, but the
cumulative screening effect is likely to increase with distance. Vegetation is
therefore likely to at least visually break the horizontal dark line.
Approximately 15km to the east of the project area is a north south running
ridgeline that forms the eastern side of the valley. This ridgeline rises
approximately 150m above the relatively flat valley floor. Due to distance it is
unlikely that this ridgeline will be significant either in contributing to landscape
character or providing an area from which an overview of the development is
possible.
Approximately 12km to the south of the project area is the settlement of Kathu
which is also located on the flat valley floor. Due to distance it is unlikely that this
settlement will be significant either in contributing to landscape character or
providing an area from which an overview of the development is possible.
3.3 LANDSCAPE QUALITY AND IMPORTANCE
The majority of the affected landscape currently appears to consist of relatively flat
topography that is covered with natural bush veld. Low intensity grazing is likely to
be the predominant agricultural activity. In areas, land owners are likely to have
diversified into game farming, hunting and bush lodges. Sparsely scattered
homesteads are likely to be apparent in the landscape.
3.4 VISUAL RECEPTORS
3.4.1 Definition
Visual Receptors are defined as “individuals and / or defined groups of people who
have the potential to be affected by the proposal”5.
It is also possible that an area might be sensitive due to an existing use. The
nature of an outlook is generally more critical to areas that are associated with
recreation, tourism and in areas where outlook is critical to land values.
3.4.2 Possible visual receptors
This section is intended to highlight possible Receptors within the landscape which,
due to use, could be sensitive to landscape change. They include;
Point Receptors that include homesteads that are scattered throughout the
area. It is likely that the focus for this area is agricultural production. Unless
farms have diversified into the tourism market it is unlikely that this group
of receptors will be overly sensitive to the likely landscape change as long as
it does not impact on agricultural productivity.
Linear Receptors that include the N14,the R380 and local routes through the
area:
5 UK Guidelines.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 17
o The N14 is a primary tourism route. Local routes surrounding the
proposed development is likely to be mainly used by local people and
relate to agricultural activities;
o The R380 which provides access to mining areas around Hotazel,
which is approximately 50km to the north of the proposed site. The
road also links to northern Namibia and because of this, it probably
carries a proportion of tourism traffic;
o Local roads including a minor road that runs to the south and south
west of the site that provides a link between the N14 and the R380;
The Kathu (Sishen) Airport is located approximately 11.7km to the
southwest of the proposed array. The airport is a regional airport with daily
SA Airlink flights to and from O R Tambo. The main concern that is likely
with regard to the airport is the potential for glint and glare affecting flights
particularly on approach to the airport.
Visual receptors will be subject to verification during the EIA phase.

4 THE NATURE OF POTENTIAL VISUAL IMPACTS
4.1 GENERAL
Impacts could include general landscape change, due to the proposed
development, as it could detract from the existing character as well as change of
view for affected people and / or activities:
a. General landscape change or degradation. This is particularly important for
protected areas where the landscape character might be deemed to be
exceptional or rare. However, it can also be important in non-protected
areas particularly where landscape character is critical to a specific broad
scale use such as tourism or just for general enjoyment of an area. This is
generally assessed by the breaking down of a landscape into components
that make up the overall character and understanding how proposed
elements may change the balance of the various elements. The height,
mass, form and colour of new elements all help to make new elements more
or less obvious as does the structure of an existing landscape which can
provide screening ability or texture that helps to assimilate new elements.
This effect is known as visual absorption capacity (VAC); and
b. Change in specific views within the affected area from which the character
of a view may be important for a specific use or enjoyment of the area:
Visual intrusion is a change in a view of a landscape that reduces the
quality of the view. This can be a highly subjective judgement.
Subjectivity has however been removed as far as is possible by
classifying the landscape character of each area and providing a
description of the change in the landscape that will occur due to the
proposed development. The subjective part of the assessment is to
define whether the impact is negative or positive. Again to make the
assessment as objective as possible, the judgement is based on the
level of dependency of the use in question on existing landscape
characteristics; and
Visual obstruction is the blocking of views or foreshortening of views.
This can generally be measured in terms of extent.
Due to the nature of the proposed development, visual impacts are expected to
relate largely to intrusion.
4.2 ZONES OF THEORETICAL VISIBILITY
Zones of Theoretical Visibility (ZTV) are defined by the UK Guidelines as “a map
usually digitally produced showing areas of land within which a development is
theoretically visible”.
The proposed order of height of the proposed array is 5m.
The ZTV analysis has been undertaken using Arc Spatial Analyst Geographic
Information System (GIS). The assessment is based on terrain data that has been
derived from satellite imagery. This data was originally prepared by the National
Aeronautics and Space Administration (NASA) and is freely available on the
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 22

The GIS Assessment does not take the curvature of the earth into account. In order
to provide an indication of the likely limit of visibility (due to this effect), a
universally accepted navigational formula has been used to calculate the likely
distance that the proposed structures might be visible over (Appendix III). This
indicates that in a flat landscape the proposed structures may be visible for the
following distances;
Approximate limit of Visibility
ELEMENT APPROXIMATE LIMIT OF VISIBILITY
Array solar PV panels 5m high 8.0 kilometres
In reality these distances could be reduced by:
Weather conditions that limit visibility. This could include hazy conditions
during fine weather as well as mist and rain; and
Scale and colour of individual elements making it difficult to differentiate
structures from the background.
4.2.1 Likely Visibility of the proposed elements
The ZTV analysis indicated on Map 5 is based on a matrix of points located
throughout the proposed development site. The analysis is therefore an indication
of the areas to which the proposed project may be visible. This analysis will be
refined in the EIA phase when the layout of the project is known. The mapping
indicates that key receptors are likely to include travellers on the N14, the R380,
other minor local roads as well as inhabitants of local homesteads.
4.3 POSSIBLE IMPLICATIONS FOR VISUAL RECEPTORS
Visual implications of the proposed project for identified receptors are likely to
include:
a) Views from Roads
The proposed development may be visible from the N14. The proposed
development is approximately 6.5km from the road. The ZTV analysis indicates
that the proposed development could potentially be seen over approximately
12.6km length of the road.
Due to the relatively flat topography, the proposed PV array is likely to be seen as
a narrow dark band in the landscape that, at this distance, is unlikely to be
obvious. It is also likely that vegetation between the road and the array is likely to
at least break views of the proposed development.
It also has to be understood that there are two additional solar PV projects that are
proposed on the same property (Remainder of the Farm Lyndoch 432) similar to
Hyperion Solar Development 2, between the proposed development and the road.
Should these projects be developed they are likely to screen Hyperion Solar
Development 2 from the road.
The project may also be visible to the R380 which at its closest is approximately
6.4km to the west of the proposed array. As with views from the N14, the proposed
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 23
array will be viewed over flat topography and through natural vegetation. The ZTV
analysis indicates that views from this road may be possible over approximately
0.9km of the road, and at a distance of approximately 7.6km. Given the
topography, screening provided by vegetation and the distance, it is highly unlikely
that the array will be visible from the R380.
The ZTV analysis indicates that views may be possible of the proposed array from
approximately 7.6km of a minor road that runs to the south and south west of the
site at a distance of approximately 7.3km. However given the flat topography, the
likelihood that at least a degree of screening will be provided by vegetation and the
distance involved, it seems highly unlikely that the proposed array will be visible
from this road.
b) Homesteads
There are fourteen (14) groups of buildings within the Approximate Limit of
Visibility of which eight (8) fall within the ZTV.
The closest homestead is approximately 500m from the edge of the proposed
development. From discussion with the Environmental Assessment Practitioner
(EAP), this homestead is inhabited by the land owner who is in agreement with the
project proceeding. In order to ensure that views from the homestead are not
totally compromised, a buffer of 500m has been allowed for in development
planning. From reference to Google Earth, the buildings seem to be orientated in a
manner that focuses outlook towards the south and away from the proposed
development.
There is a homestead approximately 2.6km to the north of the proposed array.
From Google Earth, the main house appears to be orientated east to west with
relatively dense trees on its southern side. It is therefore unlikely that it will be
possible to see the proposed array from the house. Views of the array may be
possible however from the surrounding area. However, it is likely that existing
vegetation will at least partly screen the proposed development.
There is also a group of buildings approximately 2.6km to the southeast of the
proposed array. It is possible that this could include two homesteads. However,
from Google Earth, it appears to be a single homestead with other farm buildings.
These buildings are also surrounded by trees which are likely to provide a degree of
screening. Any visual impact is also likely to be partly mitigated by distance as well
as screening that is likely to be provided by existing natural vegetation.
The remaining five groups of buildings are in excess of 3.5km from the proposed
array. It is possible that glimpses of the proposed development may be possible
from these, however, distance and intervening natural vegetation is likely to largely
screen views.
c) Kathu Airport
Kathu Airport is approximately 10.9km from the proposed array. Largely due to
distance, the proposed array is highly unlikely to be visible from the airport. It is
likely to be visible from planes on approach and exit from the airport. However,
there are other solar facilities, some of which are closer to the airport, that will also
be visible.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 24
d) Lighting Impacts
It is likely that security and operational lighting at night could make the proposed
development obvious to receptors.
4.4 LIKELY IMPLICATIONS FOR LANDSCAPE CHARACTER
As indicated in Section 4.3, the visibility of the proposed development is likely to be
limited. It is therefore unlikely to have a major influence on the character of the
landscape as experienced by the majority of people.
It is possible that glimpses of the proposed array may be possible through existing
vegetation. From reference to Map 4, it seems that other solar projects in the area
will be experienced in a similar way. The proposed development is therefore likely
to reinforce the general impression that the landscape is partly industrialised.
At night, lighting could make the proposed development obvious in the landscape.
This will be seen against the backdrop of other projects in the area. The general
area is not a pristine night time landscape as lighting is also likely to be obvious
from mining operations as well as the Kathu Airport.

5 IDENTIFIED AREAS OF POTENTIAL IMPACT
5.1 POTENTIAL VISUAL IMPACTS TO BE CONSIDERED
From the review of the proposed project, it is proposed that the following issues
should be addressed during the EIA phase;
a) The proposed development could impact on the general rural landscape
character of the area;
b) The proposed development could impact on views from roads including the
N14, the R308 and local roads;
c) The proposed development could impact on views from local homesteads;
and
d) Glint and glare associated with the proposed development could impact
negatively on the flight path into Kathu Airport.
These issues will be considered in the context of the Landscape Character Areas,
visual effects identified and the possible cumulative influence of other mining
operations.
Possible mitigation measures will also be identified.
5.2 TIMING OF POTENTIAL VISUAL IMPACTS
Impact levels are likely to gradually increase during the initial stage of
development and when the proposed facility starts to appear in the landscape. At
the end of construction, the proposed facility is likely to reach maximum visibility.
Visual impacts are then likely to be consistent throughout the operational phase,
and will reduce again as decommissioning occurs and the facility is dismantled.
5.3 INITIAL REVIEW OF POTENTIAL IMPACTS
The initial assessment is intended to provide an indication of the likely areas and
severity of impacts as well as possible strategic mitigation measures that may be
employed.
Terminology used in the initial assessment includes;
Negligible impact - small but no obvious change in landscape character;
Low impact – small and noticeable impact that will change views but will not
modify the predominant landscape character;
High impact – significant impact that will change the predominant landscape
character;
Negative Impact – a change in landscape character that is likely to
negatively affect receptors;
Positive Impact – a change in landscape character that is likely to positively
affect receptors; and
Neutral Impact – a change in landscape character that is likely to have
negligible effect on receptors.
Impact
a) The proposed development could negatively impact on the landscape character of the affected area.
The issue relates to the degradation / industrialisation of the rural landscape
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 27
character.
The proposed development area is located within an area that is perceived as being a semi-natural rural landscape. It is however being developed rapidly with other similar solar projects. However, the initial review indicates that whilst glimpses of these projects may be possible, the perception of a semi-natural landscape is likely to remain.
The proposed development is not likely to significantly change this perception. Desktop Sensitivity Analysis:

Discussion of expected significance: There is likely to be minimal additional industrial influence on surrounding landscape character as experienced by the majority of receptors. This impact is therefore likely to have a low significance.
Possible mitigation: Maintain and augment existing screening vegetation; and Colour the back face of PV panels.
Cumulative Impacts: Development of this site is likely to result in minimal cumulative impact.

A development layout and details of structure height is needed to assess the impacts as well as the identification of possible mitigation measures in any detail.
Impact b) The proposed development could negatively impact on views from roads. The issue relates to the industrialisation of the rural landscape as viewed from roads. Possible receptors include travellers on the N14, the R308 and a local road that runs
to the south and south west between the N14 and the R308. The affected sections of all roads are in excess of 6.5km from the proposed development. Due to the flat topography, the distance involved and the natural vegetation which is likely to provide a degree of screening, it is unlikely that the project will be obvious from these roads.

Impact c) The proposed development could negatively impact on views from local
homesteads. There is one homestead approximately 500m from the proposed development. However this is inhabited by the land owner and his family. It has been confirmed that
he is in agreement with the proposed development. A 500m no development area was recommended by the Visual Specialist in order to ensure that the proposed development does not completely dominate views from the homestead. This has been incorporated into the proposed layout by the developer. There is a homestead approximately 2.6km to the north of the proposed array. It is unlikely that it will be possible to see the proposed array from the house due to
existing trees around the building and its orientation. Views of the array may be possible from the surrounding area. However, it is likely that existing vegetation will
at least partly screen the proposed development. There is also a group of buildings approximately 2.6km to the southeast of the proposed array. The buildings are also surrounded by trees which are likely to provide a degree of screening. Any visual impact is also likely to be part mitigated by distance
as well as screening that is likely to be provided by existing natural vegetation. The remaining five groups of buildings are in excess of 3.5km from the proposed array. It is possible that glimpses of the proposed development may be possible from these, however, distance and intervening natural vegetation is likely to largely screen views.

Impact d) Glint and Glare as experienced from aircraft on approach to Kathu
Airport. If glint and glare is problematic, it is only likely to have an influence during early mornings and during the summer when the sun is furthest south and low on the horizon.
Due to distance and the angle at which the PV panels are set in relation to the flight path, glint and glare is unlikely to be problematic.

5.4 LIKELY SENSITIVITY OF VISUAL RECEPTORS
From the initial review of likely visual impacts, it appears that local homesteads are
the only receptors that are likely to be impacted to any significant degree.
In order to provide guidance to the applicant, the following development
recommendations have been made:
Development should not occur within 1km of homesteads outside the
development property; and
Development should not occur within 500m of the homestead within the
development property.
At these distances, with appropriate mitigation, the development should be
screened from external homesteads and should not dominate views from the
internal homestead.
Map 6, Visual Sensitivity, indicates the areas where, from a visual perspective,
development is undesirable.

Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 32
6 RECOMMENDED ASSESSMENT METHODOLOGY
6.1 REQUIREMENTS IN ACCORDANCE WITH THE WESTERN CAPE
GUIDELINES
The criterion recommended by the Western Cape Guidelines for justification of level
of input for a VIA is the expected level of visual impact. This categorisation is
derived from the following matrix;
Table 13 – Categorisation of Impact Level, Western Cape Guideline
The categorisation of development is indicated below;
The proposed development is a Category 5 development.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 33
The necessary level of assessment will be subject to the quality of the existing
landscape. The initial assessment indicates that the proposed development is likely
to largely impact areas that may be considered an area of medium scenic
significance that is already impacted by solar projects and that scenic or protected
areas are unlikely to be impacted.
The above tables indicate that the proposed development might generally be
expected to have a high visual impact. However, the initial assessment indicates
that all visual impacts are likely to be low.
It is therefore proposed that a Level 3 Assessment should be undertaken. However,
if either a high or very high impact is anticipated following the necessary site visit
then a Level 4 Assessment should be undertaken.
A Level 3 Assessment requires the following input;
Identification of issues raised in scoping phase, and site visit;
Description of the receiving environment and the proposed development;
Establishment of view catchment area, view corridors, viewpoints and
receptors;
Indication of potential visual impacts using established criteria;
Inclusion of potential lighting impacts at night;
Description of alternatives, mitigation measures and monitoring programmes;
and
Review by independent, experienced visual specialist (if required).
A Level 4 Assessment requires the following additional input;
As per Level 3 assessment, plus complete 3D modelling and simulations,
with and without mitigation.
Review by independent, experienced visual specialist (if required).
It is proposed that the assessment stage is commenced as a Level 3 Assessment. If
the proposed development is found to have significant impacts then the
assessment will be elevated to Level 4.
Confirmation of the requirement for a specialist review is required.
6.2 DETAILED METHODOLOGY
As indicated above, a site visit is required in order to investigate and finalise the
issues and impacts highlighted by this initial scoping exercise.
The following methodology will be used in preparation of the VIA report.
6.2.1 Identification of issues raised in scoping phase, and site visit
Likely issues have already been identified in this scoping analysis. These issues will
be verified from a site visit as well as response from stakeholders to the Scoping
Report.
6.2.2 Description of the receiving environment and the proposed project
The receiving environment has been described and categorised. This will be verified
as part of the site visit.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 34
6.2.3 Establishment of view catchment area, view corridors, viewpoints
and receptors
Zones of theoretical visibility and visual receptors have been established from GIS
analysis. These will be verified as part of the site visit. Existing solar project should
help to provide a useful guide as to the likely visibility of the proposed
development.
Viewpoints will be identified from a site visit to represent views of visual receptors.
6.2.4 Indication of potential visual impacts using established criteria
Areas of likely visual impacts have been identified and described from this scoping
exercise. These impacts will be verified from a site visit.
It is possible that additional impacts might be identified from the site visit and from
comments by stakeholders.
Types of identified impacts include:
General landscape degradation or changes to landscape character areas that
most people are likely to consider as negative. In this case, this could be the
introduction of a relatively large-scale development into a natural landscape.
This introduction could erode the natural character of the landscape. This is
partly a subjective judgement as it is based on the assumption that the
majority of people would prefer views over a more natural landscape (loss of
rural characteristics is rated as a negative impact). It can however be
measured in terms of likely extent of change. The influence of existing urban
areas and service related development on existing landscape character will be
assessed as part of the site visit. The area and nature of impacts associated
with the proposed development(s) will be overlaid and an assessment made as
to how these additional impacts are likely to change general landscape
character;
Change to the views of visual receptors. These impacts might relate to visual
obstruction and / or intrusion. The assessment will make judgements as to how
changes in view are likely to impact on land uses.
Impacts will be assessed using a numerical assessment system that has been
adopted by Savannah Environmental for the overall assessment. This methodology
is tried and tested, and its use will ensure that the Visual Impact Assessment can
be easily incorporated into the Environmental Impact Assessment.
6.2.5 Inclusion of potential lighting impacts at night
The impact of lighting at night will be included in the assessment using the above
criteria.
6.2.6 Description of alternatives, mitigation measures and monitoring
programmes.
The alternatives that have been identified for this project, as well as the “no-go”
alternative will be considered in the assessment.
Mitigation and monitoring measures will be developed during the preparation of the
VIA report in the EIA phase.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 35
6.2.7 Review by independent, experienced visual specialist (if required).
Confirmation of this requirement is needed.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 36
7 CONCLUSIONS
The brief scoping assessment indicates that the proposed development could have
an impact on the current landscape character and particularly the rural landscape
character of the area.
The affected landscape currently appears to be largely a semi-natural rural
character. However, there is evidence that this character is being eroded by other
additional solar energy developments in the vicinity of the proposed development.
From the desktop assessment, it seems likely that the identified surrounding
renewable energy projects are unlikely to have a significant negative visual impact
on this landscape character for the majority of sensitive receptors. This is due
generally to the distances between receptors and the projects, the relatively flat
topography and the fact that existing natural vegetation is likely to provide a
degree of screening.
The scoping assessment has indicated that the sensitive receptors for the proposed
development are likely to include:
1) Roads in the vicinity including the N14, the R308 and a local road;
2) Homesteads in the vicinity; and
3) The Kathu Airport.
Potential impacts associated with roads and homesteads relate to visual intrusion
and the general industrialisation of a semi-natural rural landscape.
The potential impact associated with Kathu Airport includes possible problems
associated with glint and glare affecting the approach flight path.
The initial assessment has indicated that;
It is possible that glimpses of the proposed development could be visible from
sections of the affected roads. However, these views are likely to be mitigated by
distance, the fact that the project will be seen in a flat landscape meaning that
there will be no overview and existing vegetation is likely to provide a degree of
screening. There is therefore only likely to be a low level of impact on the identified
roads.
There are a small number of homesteads in the vicinity of the proposed
development, the closest being in the order of 500m distance from the array.
However, this homestead is inhabited by the owner of the land on which the
proposed development is located. It is reported that the landowner is in favour of
the project as planned. A 500m buffer has been accommodated in the
development planning to ensure that the solar array does not completely dominate
the setting.
The next closest homestead is approximately 2.6km from the proposed
development. The orientation of the building, existing mature vegetation around
the homestead, the flat landscape and intervening vegetation are all likely to help
mitigate impacts.
Other homesteads are at distances of 3.6km or greater from the proposed
development.
Hyperion Solar Project Area 2, Visual Impact Scoping Report, August 2018. Page 37
It is possible that if there are tourism related uses associated with the identified
homesteads and they have greater exposure to views of the proposed development
than have been anticipated in the initial assessment, impacts could be greater than
anticipated. This will need to be verified by means of a site visit during the EIA
phase.
The proposed PV panels will face towards the north and slightly away from the
northern approach flight path into Kathu Airport. This orientation and the distance
from the flight path (approximately 9km) are both likely to mean that glint and
glare are unlikely to cause a problem for approaching aircraft.
The initial assessment therefore indicates that levels of visual impacts are likely to
be low.
The required level of assessment in accordance with the Western Cape Guidelines is
Level 4, however, the anticipated low levels of visual impact could mean that views
of the development may be difficult to see. It is recommended that a Level 3
Assessment is undertaken unless a greater level of impact seems likely from the
site visit6.
6 From a practical perspective, there is no point undertaking simulations if they do not illustrate anything.

Jon qualified as a Landscape Architect (Dip LA) at Cheltenham (UK) in 1979. He has
been a chartered member of the Landscape Institute UK since 1986. He is also a
Registered Landscape Architect and Certified Environmental Assessment Practitioner
of South Africa (2009).
During the early part of his career (1981 - 1990) He worked with Clouston (now RPS)
in Hong Kong and Australia. During this period he was called on to undertake visual
impact assessment (VIA) input to numerous environmental assessment processes for
major infrastructure projects. This work was generally based on photography with line
drawing superimposed to illustrate the extent of development visible.
He has worked in the United Kingdom (1990 - 1995) for major supermarket chains
including Sainsbury’s and prepared CAD based visual impact assessments for public
enquiries for new store development. He also prepared the VIA input to the
environmental statement for the Cardiff Bay Barrage for consideration by the UK
Parliament in the passing of the Barrage Act (1993).
His more recent VIA work (1995 to present) includes a combination of CAD and GIS
based work for a new international airport to the north of Durban, new heavy
industrial operations, overhead electrical transmission lines, mining operations in West
Africa and numerous commercial and residential developments.
VIA work undertaken during the last twelve months includes VIA input for wind energy
projects, numerous solar plant projects (CSP and PV), a new coal fired power station
as well as electrical infrastructure.
